I am suffering from extreme hair loss. My blood work shows low Vitamin D, and Ferritin in the mid 400's. Treating the low Vit. D with supplements. Went to a rheumatologist for autoimmune but all tests turned out ok. Wondering if the Ferritin has something to do with the hair loss, or what is causing the high ferritin. Any advice would be appreciated. Hair loss continues. Thanks for any insight on this issue.

Assuming you are not supplementing iron, high ferritin indicates inflammation or infection somewhere in the body. If this is your first high result ask your GP to retest in 3 months and if it is still high to do a full blood count.

Hair loss is often due to low ferritin, I've not heard of it being due to high ferritin.

Have you had thyroid function tests? Loss of hair can be due to abnormal thyroid levels.

What is your vitD result and have you been prescribed D3 or advised how much to supplement?

I think you should do some research on the effects of too much iron in the body because it isn't something that should be allowed to continue and needs more investigation by your doctor. I don't know when a high level is considered to be dangerously high.

Take Biotin. I swear by it. My hair was falling out horribly and getting thin. I take double the recommended amount and my hair has stopped falling out almost completely and my nails are long and strong. Good luck!

It could be haemchromatosis or iron overload. Hair loss is a symptom, it could eventually lead to organ damage so you need to get it checked out. Don't worry though because treatment is simple, all you have to do is donate blood regularly, no drugs.

Once you've been on a stable dose of meds for 6-8wks, see what your t3 looks like. You may have room to increase a little. My hair didn't come back until I added some t3 even though my results on levo were ideal (no conversion issues etc).

How long did it take your hair to return? Mine is paper thin and scalp now showing. Have new results coming on Monday but do not see any sign of new hair growth at all. Is there a certain number your levels have to be to see regrowth?

I don't think it took long before I saw new growth (had none while on levo and like you could see my scalp). Obvs it needs to get long enough to show among your other hair. Have you been on t3 for four weeks? I think you're looking at at least a month on *enough* t3 and it's maybe too early to say if you've hit your ideal level yet.
